Lysianasside. 
Cyphocaris, Boeck and Liitken. 
This singular genus has been recorded from the west coast of 
Greenland (C. avonyx, Boeck) by Hansen, and by Stebbing in the 
‘Challenger’ Report from Tristan d’Acunha, lat. 32° 24’ S., long. 
13° 5' W., off west coast of South America, lat. 38° 7’ S., long. 
94° 4’ W. (C. micronyx), and 400 miles north of the Sandwich 
Islands (C. challenger). As the latter author informs me that he 
has now merged C. micronyx in C. ANONYX, this species has a truly 
enormous range. The ‘Challenger’ specimens were taken at a 
depth of 1425 and 1500 fath. respectively. Also taken by the 
Prince of Monaco in lat. 47° 38’ N., long. 22°13' W., depth 13800 m. 
(Chevreux, Camp. de ‘ l’Hirondelle, 1900, p. 165). 
Orchomenopsis, G. O. Sars, 1895*. 
This genus was separated by G. O. Sars from Orchomene on 
account of slight differences in structure. It includes two, and 
perhaps all three, of the ‘ Challenger’ species, and one (0. robusta, 
Sars) from the coast of Norway in 100 fath. The localities of the 
‘ Challenger’ species are as follows :—South of Japan, lat. 26° 29'N., 
long. 137° 57’ E., 2425 fath. (O. musculosus); east of Buenos 
Ayres, lat. 35° 39’ §., long. 50° 47’ W., 1900 fath. (0. aByYsso- 
kum); Kerguelen Island, Betsy Cove, surface, and off Cumberland 
Bay, 127 fath. (0. excavatus). O. abyssorum is also recorded by 
M. Chevreux from lat. 48° 24’ N., long. 20° 38’ W., depth 2200 m, 
(Camp. de ‘l’Hirondelle,’ p. 23).

* Since the above was written, the author has met with two new 
species in a collection made by Mr. Fougner during the ‘Southern Cross’ 
expedition to the Antarctic Seas in 1899-1900, and described in a paper 
read before the Linnean Society on Dec. 18, 1902. These are O. nodi- 
manus, Cape Adare, lat. 71° 18’ S., lone. 170° 9' W., dredged in 26 fath., 
and O. Rossi, from lat. 78° 35’ S., long. 164° 32' W., taken near the 
surface. M. Chevreux also has described (Bull. Soc. Zool. de'France, 
1903, tome xxviii. pp. 98-96) two new species from the N. Atlantic,
